From an economics student, well done! Totally agree with you that this model is appropriate and makes sense. Those people saying it does not apply are either retarded or do not understand the concept. Game theory relates to human behaviour REGARDLESS of what they are doing, it DOES apply to people playing computer games because, well, playing a computer game does not make you act any less human in regards to decision making. Risk and reward is not exclusive to real-world interactions. That being said, humans dont always act logically on this game. I utterly despise some DayZ bandits ^^ Not because of the ones who kill for gear, which I suppose makes sense, but the ones who kill when it is clearly not in their interests to do so. Yesterday I was playing with my friend and I heard him disclaim, "Oh my god, is that you or somone else?" I spun around to find a survivor standing next to my friend who shot me dead... Fair enough I get that he probably wanted my gear and beans. What I do not understand is why he walked up to my friend, looked at him, looked at me, then shot me. There is only ONE outcome to him approaching us and shooting one of us down. He gets killed by my friend the instant after shooting me. This means he dies, I die and my friend gets all his loot (he was loaded with supplies and a good weapon), and I can retrieve mine after I finally manage to slog my way back to where we were. Where is the logic? If he wanted to kill us both and take our stuff, he should have stayed away and picked us off with his rifle; he could see us easily from the tree line, we were in a clearing. But if he shot because he felt threatened by us, why did he not try to hail us or even approach us in the first place? Logic fail, he lost everything and all we lost was the 30 minutes it took me to get back. If anything, we won due to the stuff we got off him. WHERE IS THE LOGIC? Sorry, rant off. I dont understand why he did that ^^ It seems in some cases rational behaviour completely bypasses some people. As always there are exceptions to the rule.
